We get to see that Walt Disney has produced a majority of the highest grossing films, with all of them being rated PG-13/PG/G. Even with other studios, we see these ratings are the only to show up. This is most likely due to reaching a wider audience under these ratings as younger kid and pre-teens would bring their parent/s to the movie as well, resulting in more ticket sales and a larger box office. Action/Adventure movies are big and since superhero movies fall into these categories, we can assume big box offices.

The number of tickets sold does not seem to have any effect on the average ticket price.

We can slowly see a bit of a decline in the tickets sold as we move deeper into the information era, where people have an easier access to illegally watch movies. Nevertheless, the black line is when countries started going into lockdowns and we see a 8-9bn drop in box office. Which was very big for Hollywood, that being said we also saw many movies being delayed and pushed back. The loss won't be recouped as when the delayed movies are released in the future, they will be competing with new movies which will just split the box office.

We see number of wide releases drop in 2020 due to movies getting pushed back to 2021 or 2022, thus seeing a jump in 2021.
